Someone who is aggressive is forceful or tends toward the use of aggression. This is not someone you’d usually want to be around, particularly if they are trying to sell you insurance or a used car.
I usually walk out of stores without buying anything when faced with aggressive salespeople. I don’t respond well to aggressive.
A passive aggressive person is someone who is aggressive, but not directly so. Their aggression might take the form of whimpering, whining or pouting or intentionally deferring activities to annoy people.
Fine. Be that way. See how you like it when I’m passive aggressive toward you.
